Steel Fire Rated Doors

Your Fire Rated Door, 30-240min Certified, configured & built to order from your specification to your satisfaction - Internal or external use

Steel Fire Rated Doors - Tested to BS 476 Parts 20 & 22

Our Fire Rated Steel Doors and Fire Exits have been independently 3rd party tested and offer certification in excess of 6 hours.

We are able to offer a large range of hardware options as the door has been tested both ‘latched’ and ‘unlatched’. The door is manufactured from 1.5mm zintec steel as standard making it both strong and secure.

Fire Doors are manufactured to suit many applications such as:

  • Warehouses
  • Flat Entrances
  • Server and Document Rooms
  • Schools
  • Vaults
  • Retail Outlets
  • Store Rooms
  • Offices

A wide range of additional hardware is available, as well as fire rated glass (Firelite) for when you require a vision panel in your fire rated doors and louvred doors for when airflow is key. Our fire rated doors comply with all necessary regulations in the UK for their application in any building.

Every one of our fire rated doors is manufactured in the UK from high grade, superior quality steel, finished in your choice of RAL colour PPC and delivered straight to your site.
